3 Description

The TPS7C84-Q1 is a wide input, low-dropout

regulator (LDO) supporting a 2.1V to 40V input

voltage range and up to 150mA of load current. The

TPS7C84-Q1 has both fixed and adjustable output

types. Fixed output options include 3.3V and 5V. The

output is able to be set between 1.2V and 39V with

the adjustable device.

This device has a power-good (PG) output that

monitors the voltage at the feedback pin to indicate

the status of the output voltage. The EN input and

PG output sequence multiple power supplies in the

system.

The TPS7C84-Q1 is designed for up to 40V VIN

battery-connected applications. The wide output

voltage range allows the device to generate the bias

voltage for silicon carbide (SiC) gate drivers and

microphones as well as power MCUs and processors.

The device is available in both an SOIC package

and a small VSON package with wettable flanks

that facilitates a compact printed circuit board (PCB)

design. The low thermal resistance enables sustained

operation despite significant dissipation across the

device.
